Agilent Technologies 5000 Series manual TRIGgerPATTern, Mask, the edge takes precedence

Commands by Subsystem 3

:TRIGger:PATTern

(see page 530)

Command Syntax :TRIGger:PATTern <pattern>

<pattern> ::= <value>, <mask> [, <edge source>, <edge>] <value> ::= integer in NR1 format or <string>

<mask> ::= integer in NR1 format or <string>

<string> ::= "0xnn"; n ::= {0,..,9 A,..,F}

(# bits = # channels, see following table) <edge source> ::= {CHANnel<n> EXTernal NONE}

<n> ::= {1 2 3 4} for the four channel oscilloscope models <n> ::= {1 2} for the two channel oscilloscope models

<edge> ::= {POSitive NEGative}

The :TRIGger:PATTern command defines the specified pattern resource according to the value and the mask. For both <value> and <mask>, each bit corresponds to a possible trigger channel. The bit assignments vary by instrument:

Oscilloscope Models	Value and Mask Bit Assignments
4 analog channels	Bits 0 through 3 - analog channels 1 through 4.
	Bit 4 - external trigger.
2 analog channels	Bits 0 and 1 - analog channels 1 and 2. Bit 4 -
	external trigger.

	Set a <value> bit to "0" to set the pattern for the corresponding channel to
	low. Set a <value> bit to "1" to set the pattern to high.
	Set a <mask> bit to "0" to ignore the data for the corresponding channel.
	Only channels with a "1" set on the appropriate mask bit are used.
	The optional source and the optional edge should be sent together or not at all. The edge
N O T E
	will be set in the simple pattern if it is included. If the edge source is also specified in the
	mask, the edge takes precedence.
Query Syntax	:TRIGger:PATTern?
	The :TRIGger:PATTern? query returns the pattern value, the mask, and the
	edge of interest in the simple pattern.
Return Format	<pattern><NL>
